replace your zuni pox with one with crit and another affix like avg dmg/vit/socket/% life or crit/ias for a trifecta if you want to go balls out

your hellfire ring isn't too great for your heroscore though I understand that you would probably want to use it for farming. But if you're looking at just upping your heroscore then get another ring with int/cc/cd and whatever other useful affixes you can find are a bonus
